Twitter Card vs OG Image — What's the Difference?
They look the same in your feed, but they're powered by completely different meta tags. Here's what you need to know, and why using both is the safest bet.
TL;DR — The Short Answer
OG images use og:imagemeta tags (Facebook's Open Graph protocol).Twitter Cards use twitter:imagemeta tags (Twitter's own system).
Twitter actually falls backto og:image if you don't set twitter:image, so you technically only need OG tags. But setting both is the safest approach because Twitter's fallback behavior isn't guaranteed and may change.
What Are OG Images?
Open Graph (OG)is a protocol created by Facebook in 2010 that lets any web page become a "rich object" in a social graph. It defines a set of meta tags that describe the page's title, description, type, and preview image.
<meta property="og:title" content="Your Page Title" /> <meta property="og:description" content="Your description" /> <meta property="og:image" content="https://yoursite.com/og.png" /> <meta property="og:url" content="https://yoursite.com/page" /> <meta property="og:type" content="website" />
The og:image tag is the most important one. It controls what image appears when someone shares your link on any platform that supports Open Graph — which includes Facebook, LinkedIn, Discord, Slack, WhatsApp, iMessage, and many others.
The recommended image size is 1200 x 630 pixels with a 1.91:1 aspect ratio.
What Are Twitter Cards?
Twitter Cardsare Twitter's own system for attaching rich media previews to tweets that contain links. They work similarly to OG tags but use a different namespace: twitter: instead of og:.
<meta name="twitter:card" content="summary_large_image" /> <meta name="twitter:title" content="Your Page Title" /> <meta name="twitter:description" content="Your description" /> <meta name="twitter:image" content="https://yoursite.com/twitter.png" />
There are four types of Twitter Cards:
- summary_large_image — large preview image (recommended, matches OG image dimensions at 1200x630)
- summary — small thumbnail image (1:1 square, 120x120 minimum)
- app — promotes a mobile app with install button
- player — embeddable video/audio player
For most websites, summary_large_image is the right choice. It produces a preview that looks nearly identical to OG link previews on other platforms.
Side-by-Side Comparison
| Feature | OG Image | Twitter Card |
|---|---|---|
| Created by | Facebook (2010) | Twitter (2012) |
| Meta tag format | <meta property="og:..."> | <meta name="twitter:..."> |
| Image tag | og:image | twitter:image |
| Recommended size | 1200 x 630 | 1200 x 630 (summary_large_image) |
| Used by | Facebook, LinkedIn, Discord, Slack, WhatsApp, iMessage | Twitter/X only |
| Fallback | None — platforms that don't support OG show no preview | Falls back to og:image if twitter:image is missing |
| Image can differ | Yes — you can set a different image for Twitter | Yes — twitter:image overrides og:image on Twitter |
Why You Should Use Both
Twitter currently falls back to og:image iftwitter:image is not set. So why bother setting both?
- Fallback isn't guaranteed.Twitter's documentation says it uses og:image as a fallback, but this behavior could change without notice. Explicit tags are safer.
- You might want different images. Maybe your OG image includes branding that works on Facebook but you want a cleaner version for Twitter. Setting both tags lets you customize per-platform.
- Some Twitter cards behave oddly without explicit tags. In testing, pages with only OG tags sometimes show the small summary card instead of summary_large_image. Setting
twitter:cardexplicitly prevents this. - It takes 30 seconds. Adding 4 extra meta tags costs nothing and eliminates a class of social preview bugs.
How to Set Up Both (Copy-Paste Code)
Here's the complete set of meta tags to add to your page's <head>:
<!-- Open Graph (Facebook, LinkedIn, Discord, etc.) --> <meta property="og:title" content="Your Page Title" /> <meta property="og:description" content="Your page description" /> <meta property="og:image" content="https://yoursite.com/og.png" /> <meta property="og:url" content="https://yoursite.com/page" /> <meta property="og:type" content="website" /> <!-- Twitter Card --> <meta name="twitter:card" content="summary_large_image" /> <meta name="twitter:title" content="Your Page Title" /> <meta name="twitter:description" content="Your page description" /> <meta name="twitter:image" content="https://yoursite.com/og.png" />
Note: in most cases, you can use the same image URL for bothog:image andtwitter:image. Use the same 1200x630 image.
How to Test Your Setup
After adding the meta tags, test your setup with these tools:
- Facebook Sharing Debugger: Go to developers.facebook.com/tools/debug — paste your URL to see how it renders on Facebook.
- Twitter Card Validator: Go to cards-dev.twitter.com/validator — paste your URL to preview the Twitter Card.
- LinkedIn Post Inspector: Go to www.linkedin.com/post-inspector — paste your URL to see the LinkedIn preview.
- Manual test: Paste your URL into Discord, Slack, or iMessage and see if the preview card appears correctly.

Do I need both OG images and Twitter Cards?
Twitter falls back to og:image if twitter:image isn't set, so you technically don't need both. But setting both explicitly is safer and takes only a few extra meta tags.
Can I use the same image for OG and Twitter?
Yes. Both OG images and Twitter summary_large_image cards use the same recommended dimensions of 1200 x 630 pixels. One image works for both.
Why does my Twitter Card show as a small thumbnail instead of large image?
Make sure you include <meta name="twitter:card" content="summary_large_image" />. Without this tag, Twitter may default to the small summary card type.
What happens if my OG image is the wrong size?
Most platforms will crop or resize it automatically, which can cut off important content or make it look blurry. Always use 1200 x 630 for the best results.
